  • This paper proposes a qualitative reasoning approach for the spatial configuration of mechanisms that could be applied in the early phase of the conceptual design. The spatial configuration problem addressed in this paper involves the relative direction and position between the input and output motion, and the orientation of the constituent primitive mechanisms of a mechanism. The knowledge of spatial configuration of a primitive mechanism is represented in a matrix form called spatial configuration matrix. This matrix provides a compact and convenient representation scheme for the spatial knowledge, and facilitates the manipulation of the relevant spatial knowledge. Using this spatial knowledge of the constituent primitive mechanisms, the overall configuration of a mechanism is described and identified by a spatial configuration state matrix. This matrix is obtained by using a qualitative reasoning method based on sign algebra and is used to represent the qualitative behavior of the mechanism. The matrix-based representation scheme allows handling the involved spatial knowledge simultaneously and the proposed reasoning method enables the designer to predict the spatial behavior of a mechanism without knowing specific dimension of the components of the mechanism.

  • Institutional foodservice is a type of meal provided to workers in industry and affects the health and psychological wellbeing of workers and productivity. Thus, research on customer satisfaction with institutional foodservice is important. In addition to food industry and food culture developments, the requirements of institutional foodservice customers are diversifying due to COVID-19. Therefore, the purpose of this study was to identify factors that affect customer satisfaction with institutional foodservice using a user-based approach. In this study, the quality of institutional foodservice was defined using customer satisfaction or dissatisfaction, and by using in-depth interview and open coding (a qualitative research method), we derived qualities of institutional foodservice from the user's perspective and compared these with those of previous studies. This study is meaningful as the quality of institutional foodservice was analyzed using a user-based approach, in-depth interview, and open coding and compares results with those of previous studies.

  • Objectives: Children with disabilities may exhibit a multitude of symptoms, and treatment requires a multidisciplinary approach for a satisfactory outcome. Lack of awareness among physicians, lack of referral, and lack of inter-sectoral coordination have hindered paediatric practice in Tamil Nadu, a state in India with a striking childhood disability rate that warrants a timely interdisciplinary approach. However, the perspectives of paediatricians on paediatric physiotherapy are unknown. The aim of the study was to investigate the perspectives of practicing paediatric physicians in Chennai on the role of physiotherapy in paediatrics. Methods: For an in-depth exploration, qualitative semi-structured interviews were conducted in person with 10 paediatricians. Audio from the sessions was recorded and transcribed, and data saturation was achieved through iterative analysis. Results: A grounded theory analysis of the results yielded 5 domains under which the perspectives and expectations of the physicians were described, along with the barriers experienced by patients' parents as explained by their paediatrician. The responses highlighted deficits in awareness, structural support, accessibility and direct communication between physicians and physiotherapists. Conclusions: Paediatric physicians have different opinions, and some ignorance persists concerning paediatric physiotherapy. This study warrants a proper structure of the paediatric rehabilitation unit and regular interdisciplinary meetings and focus group discussions to increase access for parents and improve patient outcomes.

  • In spite of the bad conditions of fashion companies: the number of licit wear consumers in Korea are increasing because knit wear gives a body with an comfort action. Domestic knit wear industry, however, doesn't have any standard fur satisfying consumers'needs and for quality estimation on that. So we examined the knit wearers'conception of the quality to broaden the knowledge of knit wear and produce better products. The purpose of this study was to find out the factors of wearer's perception. This study carried out through a qualitative approach. The subject of this study were 17 single women who were 20's and living in Seoul and Kyoungki province. The item of this questionary was as follow: 1) what they know about knit wear and how much they are satisfied with that 2) what the wearers think the problems of knit wear are 3) how knitted wear industry can satisfy consumers's needs and take into account consumer feedback in product development The results of this study were summarized as follows. 1. The wearers had no knowledge about materials, sewing methods, patterns, knitting methods, and gage. 2 The wearers didn't recognize the differences between the products by famous brand and obscure conventional market. For that reason, the high price knit wear wont satisfy wearer. 3. The wearers didn't prefer the revealing their body shapes. 4. Laundering was the big problem which was they chosen the knit wear. They take it for granted that the knit wear needs dry-cleaning or hand-washing. Knit wear industry tries to make it easy laundering by development knit material.

  • This study originates from the following problematic: Can a social history of design provide a useful methodology for the research and education of Korean design? For the understanding of the modes of socio-cultural approach to design, the chapter 2 compares the narrative mode of designer-centered history promulgated under the influence of Nikolaus Pevsner and that of socio-cultural approach advocated by Adrian Forty. The chapter 3 studies the cases of socio-cultural approach to Korean design through the domestic exhibitions like 'Everyday Life, Memory and History,' 'A Glimpse into the Society through Campaigns,' and 'Design Culture in Korea 1910-1960' which attempted the socio-cultural approach to the visual culture of modern/contemporary Korea. In the chapter 4, this study investigates into the meanings and characteristics of socio-cultural approach in the design research and education, End argues for the necessity of the introduction of qualitative research methodology.

  • The implementation of NIR and chemometrics in the Pharmaceutical industries is still in strong progress, both regarding qualitative and quantitative applications and beneficial results are seen. Looking at the development so far, NIR will change the pharmaceutical industry even more in the future. This presentation will address the experiences and progress achieved regarding the application and implementation of quantitative methods for determination of content uniformity and assay of tablets with less than 10% w/w of active, using Near Infrared transmittance spectroscopy in combination with PLS. Also qualitative methods for identification of the same tablets by Near Infrared reflectance spectroscopy will be discussed. Four commercial tablet strengths are formulated and produced from two different compositions by direct compression. Three different strengths are dose proportional, i.e. fixed concentration by varying in size. The aim was to replace the conventional primary methods for analysing content uniformity, assay and identification by NIR. Studies were performed on comparing transmittance versus reflectance spectroscopy for both applications on the dose proportional tablets. The model for determination of content uniformity and assay was developed to cover both coated and uncoated tablets, whereas the qualitative model was developed to identify coated tablets only. The impact of the tablet formulation, tablet size and coating, resulted in individual models far each composition The best calibration was achieved using diffuse reflectance for the identification purposes and diffuse transmittance for the quantitative determination of the active content within the tablets. As NIR in combination with other techniques opens up the possibility of total quality management within the production, the transfer of the above-mentioned models from a laboratory based approach to an at-line approach at H.Lundbeck will be addressed too.

  • This paper takes a qualitative approach to examining liveability by analysing the participatory planning proposals delivered by the local residents in Daegu, South Korea. Drawing on the textual resources of the proposals and interview data, the perceived liveability was found to vary across different neighbourhoods, and community cohesion and community capacity building were found highly valued in the liveability discourses in the Korean context. The paper argues that our understandings of liveability should be localised and contextualised at a sub-municipal level. It also highlights that participatory planning can be useful in articulating local communities' perception and experiences of liveability of their immediate localities, particularly in the less attractive and less affluent neighbourhoods in the city.
